The Institute of Electrical and Electronics Engineers (IEEE) appointed Professor Thomas Bäck as an IEEE Fellow in the class of 2022. Bäck is becoming a Fellow for his contributions in synthesising evolutionary computation. Less than 0.1% of voting members are selected each year for this member grade…

Thanks to a €4.8 million grant from the Dutch Research Council, a consortium that includes four physicists from Leiden University will develop a national facility for atomic-scale research into novel materials. This initiative is expected to drive innovation for energy transition.

The Netherlands has DigiD, Portugal ‘de Cartão de Cidadão’, and Ireland MyGovID. Europe now wants one uniform digital identity card - the same for all Member States. For the Dutch government, the European successor to DigiD is a prestige project. State Secretary Van Huffelen wants to roll out an app…

Tim van de Meerendonk explores how farmers, insurance advisors and local politicians in India try to make sense of insurance figures through their moral convictions.

On September 5, at the festive opening of the Faculty Year, a range of new murals will be officially presented in the Van Steenis’ Reuvens Hall. The wall paintings reflect a variety of Dutch soil stratigraphies, from Oss to burial mounds. Aside from being a striking new addition to our Faculty building,…

The European Research Council (ERC) has awarded a prestigious Starting Grant to Leiden archaeologist Dr Nathalie Brusgaard. With this €1.5 million grant, Brusgaard will investigate how the transition to farming in Western Europe affected the relationship between humans and wild animals. A theme that,…

Amidst the lathes and welding machines of the Fine Mechanics Department, Emiel Wiegers is working concentratedly on a metal cylinder. He and his colleagues design and construct components for researchers' set-ups. ‘We are a bunch of inventors who enjoy helping the researchers in our Faculty.’

Defending your PhD research in front of nearly 300 elementary school students: that was the challenge faced by PhD candidates Jo-Anne Verschoor and Marinka de Willigen during the VUURVLIEGEN competition organised by the Centrum JongerenCommunicatie Chemie (C3). After an exciting competition, the children…

What defence strategy should the Dutch government adopt for the next four years? Our experts advise investing in social resilience, strengthening ‘soft power’ and integrating defence awareness into education.

A suitcase as a messenger of quantum science. That is the idea behind QuanTour, a project connecting researchers from 12 European universities. In December, the suitcase landed in Leiden. A month later, it is time to pass the baton to Copenhagen. But what happened to it in Leiden?

The shock wave triggered by one of the five galaxies making up the iconic Stephan’s Quintet appears to be less disruptive than previously thought, with the shock likely being cushioned by dust particles in the surrounding gas.
